ISO 4254-1:20 13规定了农业中使用的自行式乘坐式机器、安装式、半安装式和牵引式机器的设计和构造的安全要求及其验证方法，以应对大多数机器的典型危险。此外，它还规定了制造商提供的有关安全工作实践的信息类型，包括有关剩余风险的信息。 本文件涉及在正常操作和维修过程中按预期使用以及在制造商可预见的误用条件下使用时与该农业机械相关的重大危害、危险情况和事件。 ISO 4254-1:20 13不适用于 ？农业或林业拖拉机、 ？用于农业的飞机和气垫车， ？草坪和园林设备， ？机器特定的组件或功能（例如，工作工具和/或过程）。 ISO 4254-1:20 13不适用于与定期服务、机器转换和由专业服务人员进行的维修相关的危害、环境危害、道路安全（如转向、制动）或动力输出轴（PTO）；也不适用于输电用运动部件的防护装置，但防护装置和屏障的强度要求除外。 ISO 4254-1:20 13不适用于在其发布日期之前制造的机器。 并非ISO 4254-1:20 13处理的所有危害都必须存在于特定机器上。制造商应进行风险评估，以确定适用的危害以及除本部分或相关机器处理的危害之外的任何危害-具体部分。ISO 4254机器特定部分的要求优先于该部分的要求。

ISO 4254-1:2013 specifies the safety requirements and the means of their verification for the design and construction of self-propelled ride-on machines, mounted, semi-mounted and trailed machines used in agriculture in order to deal with the hazards which are typical for most of the machines. In addition, it specifies the type of information on safe working practices including information about residual risks to be provided by the manufacturer. This document deals with significant hazards, hazardous situations and events relevant to this agricultural machinery when used as intended and under the conditions of misuse foreseeable by the manufacturer during normal operation and service. ISO 4254-1:2013 is not applicable to

• ? agricultural or forestry tractors,
• ? aircraft and air-cushion vehicles used in agriculture,
• ? lawn and garden equipment,
• ? machine-specific components or functions (e.g. working tools and/or processes).

ISO 4254-1:2013 is not applicable to hazards related to periodic service, machine conversion and repairs intended to be carried out by professional service personnel, environmental hazards, road safety (e.g. steering, braking), or to the power take-off (PTO) drive shaft; neither is it applicable to guards of moving parts for power transmission except for strength requirements for guards and barriers. ISO 4254-1:2013 is not applicable to machines which are manufactured before the date of its publication. Not all of the hazards dealt with by ISO 4254-1:2013 are necessarily present on a particular machine. A risk assessment should be carried out by the manufacturer to determine the hazards that are applicable and any hazards in addition to those dealt with by this part or a relevant machine-specific part. The requirements of a machine-specific part of ISO 4254 take precedence over the requirements of this part.
